The related sport of ice stock sport (eisstockschießen in German) was a demonstration event in 1936 and 1964. These events are not considered additional demonstrations of curling.
Two events are contested, the men's and women's. A third, mixed doubles, was considered for inclusion in the 2010 Winter Olympics. However, it was rejected because the Olympic Programme Commission felt it had not developed enough. Mixed doubles was approved for inclusion in the 2018 Winter Olympics following an IOC Executive Board meeting in June 2015.
